I sometimes like to add a little more depth into my drawings than having single paths be of a single fill. In the illustration below, for example, I have two balls drawn.

The first was made the way I was taught. A stroke and fill - all consisting of one path. The second, I tried something different to help show more depth, but it consists of three paths. A black stroke with no fill, a dark red fill with no stroke, and a background red fill with no stroke. The first way was easier since I could add a stroke and fill to the same path, but I can't capture more details that way if extra colors touch the stroke. And if I were add paths on top of an object, then I would have to be too percise so they don't overlap the stroke. This second way, I at least have a stroke to draw behind.

Is this making sense to people? I want check here to see if there's an easier way to do this. Making an object that only consists of an outline and not a fills doesn't seem right if it is meant to include a fill. Any help?
